You probably know all about the explorer backpacks little ones and mini adventurers can pick up at the gates at the Cambridge Botanic Garden. But did you know that this month they’ll be stuffed with new, quirkily illustrated plant-spotting activity trails?

Aside from the usual binoculars, pencils, clipboard and bug viewer, this summer there will also be one of four expedition routes for the garden – and each Friday there’ll be a new one.

The first was Be a Bee (be quick and you’ll still be able to catch it – until Thursday at least!), packed with challenges for spotting buzzy bees in the Rose Garden and Bee Borders, tips on collecting propolis from pine trees (they use it as glue for their hive), and you can discover where a carder bumble bee has collected fluff from lamb’s ear leaves to make its home cosy.

Week two is a chance to see how we interact with the vegetation and creatures that live in the garden. The PAH trail (Plants, Animals and Humans), will lead you past a shrew loo in the Glasshouse (it’s super clever), and plants that collect rainwater in their leaves to make paddling pools for poison arrow frogs and their tadpoles – nifty!

In the third week, budding Attenboroughs can rate the superpowers of plants around the garden, “from the most poisonous to the most explosive,” apparently, and in week four, you can pick up a plant passport and travel the world within the Garden, collecting stamps and finding out just how far some of the plants have travelled to get here.

The trails change every Friday and are suitable for 3-15-year-olds to get stuck into.
